To all whom itmag concern:

Be it known that I, THOMAS LEONARD BARKS, a subject of the King of Great Britain, residing at 38 Victoria street, London, England, have invented a new and useful Roofing-Bar, of which the following is a specification.

My invention relates to a new and improved form of roofing bar to be used in connection with roof glazing or other roofing materials, and it has for its objects, first, to provide a bar that is simple of construction, and cheap; second, to provide a roofing bar of very strong channel section of U shape with condensation channels or guttersand special grooves for taking lead cushioning pipe or similar material to allow of the glazing or other roofing material being held firmly in position; and third, to provide a roofing bar fitted with special brackets at intervals on the inside of the channel section adapted to support and hold in position suitable bolts 0r studs for securing a furtl er light channel section bar of galvanized iron or the like, to bear down on and secure the glazing or other roofing materialand at the same time provide a watertight joint. Though this bar can be used with any roofing material that is to be laid in sheets, it is especially well adapted for use in the roof glazing of railway stations, car sheds, electric power stations, factories, mills, winter gardens, verandas, conservatories, green houses, baths, arcades, schools, hotels, garages, studios and the like, and may be fixed at any angle.

It will be seen that my bar is very light and very strong. It is made preferably of steel, and if desired-the bar capping, studs and brackets maybe lead covered, copper plated or otherwise treated to prevent corrosion. A roof constructed with this bar will carry a great snow weight, and breakage on account of expansion and contraction of the roofing sheets is impossible. By resting each pane or sheet of roofing on a soft bed of lead tubing, breakage is avoided even when the surface is uneven. The condensation channels carry any moisture that gathers, down to the ground or the outside gutters. All bolts and nuts being detachable, it is an easy matter to make repairs in case of accident to any of the glazing, and not a bar need be removed.

Figure l is a perspective view of my bar showing one of the brackets and the roofing sheets held in place; Fig. 2 isa cross section of my bar through one of the brackets in the channel, showing the roofing sheets held in place; Fig. 3'is an end view of my bar showing the end plate for preventing the glazing or other roofing material from slipping, and the method of fastening the said plate, and showing a modification in the form of a superimposed rod or bar adapted to receive boards thereon for the purposes of repair and the like, and showing the further modification of the upright portion of the bracket lengthened to reach the bottom of the channel; Fig. 4 is a cross section on line IVIV of Fig. 3; Fig. 5 is a plan view from the top, of the parts shown in Figs. 8 and 4.

Similar letters refer to similar parts throughout the several views.

Fig. 1 represents a perspective View of my fiat bottomed U section roofing bar of steel or other suitable material; 1 being the U section steel bar; 2 the condensation channel or gutter; 3 is a channel fitted with soft lead cushioning pipe in position, or other suitable cushioning material; 4 is the bracket afiixed to the inside of the U section by the bolt 5, which is passed through an aperture in the said U section and through an aperture in the said bracket registering therewith, and held in place by the nut 6; 7 is a supporting stud or post for securing the capping 11, and the said stud being equipped with a thread at each end and is shown with its lower end screwed into the bracket 4. through a threaded aperture therein; 8 is a washer of lead or other suitable material; 9 is a nut screwed to the upper end of the stud or post 7 and securing the capping 11; 10 shows the glazing or other roofing material secured in position and resting on the cushioning pipe 3; 12 is the end plate fitted to prevent slipping of the glazing or other roofing material; 13 are lugs on the said end plate which lugs fit in slots cut in the condensation channel and after the end plate 12 has been placed in position the lugs 13 are bent back at right angles, one in one direction and the other in the opposite direction as shown in Fig. 5; 14L are the slots in the channels 2; 15 is a pipe or bar affording means for placing planks or ladders across the roofing to allow of easy replacement and repair of the roofing, the said pipe or bar being held in place by extending the stud 7 beyond the capping 11 and through an aperture in the said pipe It is obvious that the post or stud 7 may I just as well be riveted to the bracket 4:, a

modification shown in Figs. 3 and 4:. This would be an advantage in putting up the bars and would prevent unscrewing the bolts from the brackets when removing the nut 9 in repair work.

The nut 6 is preferably rectangular and the bracket 4 is to be aifixed to the inside of the channel of the bar by screwing the bolt 5 through apertures in the side of the bar and in the bracket into the nut 6. Thus the flat side of the said nut will lie flush with one side of the angle of bracket l. Consequently it cannot be turned or loosened. It will be seen also that the bracket 4 may be extended at the upright side thereof until it reaches the bottom of channel bar 1. This construction will insure the rigidity of the bracket and the post 7' when once the bolt 5 has been driven home, and so facilitate laying the roofing. It has the further advantage of diverting any pressure exerted on the bar 15, from the roofing 10 and bolt 5 and throwing it on the strong channel bar 1.

While I have illustrated and described only one specific embodiment of my invention, I am aware that it is susceptible of modification and I do not desire to be limited to the precise form shown.

and hold an end plate, an end plate equipped at the sides thereof with lugs adapted to pass through the said slotsand providing means for fastening the said end plate'at the end of the said bar;the said baralso fitted with channels forsupporting cushioning on which the roofing material rests, tubular cushioning, brackets with means ofafiixing the same at intervals inside the trough of the said bar, each of the said brackets being equipped with means of receiving and holdmg fast an upright post or stud, posts or studs with means of affixing the same to the said brackets and being provided with threads at their upper ends, a resilient bar of channel section having apertures at inter- 1.-

vals; adapted to receive the said posts, washers, and nuts fitting the threads of the upper ends of the said studs adapted to hold in place the said resilient channel bar against the upper surface of the roofing ma terial used.
